A.T.& T.CO. | Customer | U.S.A. | American Telephone & Telegraph Company | 1885 | 1915 | McD, p149 |
A.U. | Customer | U.S.A. | American Union. Produced by both Hemingray and Brookfield | |||
AM.INSULATOR CO. | Manufacturer | U.S.A. | Probably a Manufacterer, not supply house. They were produced under some sort of arrangement at the American Iron Glass Pipe and Plate Co in Haverhill, Mass., but Am. Ins. Co. was a glass company responsible for producing insulators, not a telegraph supply house. And not all the evidence is 100% convincing. For one thing, American was around at least as early as mid-1883, while the Iron glass works wasn't in operation until December of 1884. That's a long time to be in business and not deliver any products to your customers. | 1883 | 1886 | McD, p37 |
AM.TEL.& TEL.CO. | Customer | U.S.A. | American Telephone & Telegraph Company | 1885 | 1915 | McD, p149 |

BOSTON BOTTLE WORKS | Manufacturer | U.S.A. | Boston Bottle Works | 1871 | 1877 | McD, p32 |
BROOKE'S | Manufacturer | U.S.A. | Depends on if it's the Brooke's Patent insulators or the Ellenville ones that say ""Homer Brooke's Pat. Aug. 14, 1883. Homer Brooke patented a glass press 1/25/1870, which was purchased by Brookfield. The 8/14/1883 date refers to a patent issued to Matthew Johnson. Apparently Johnson and Brooke were both influential at the Ellenville NY glass co and that's where those insulators come from (according to Ray Klingensmith.) | |||
BROOKFIELD | Manufacturer | U.S.A. | Brookfield | 1869 | 1921 | McD, p24 |

C.E.L.CO. | Customer | U.S.A. | Cambridge Electric Light Co, user (some say California Electric Light Co, but the insulators bear all the hallmarks of Pennycuick, a Boston manufacturer. Plus, early collectors claim these were extensively used in Cambridge and the Boston area, and very few have turned up in California.) | 1885 | 1900 | McD, p58 |
C.E.W. | Supply House | U.S.A. | California Electrical Works. This was a supply house, and most likely were produced by local glass co; some insist that CEW actually owned their own glass works, but there's scant evidence to that effect. Same thing for EC&M, which was CEW's predecessor. | 1877 | 1908 | McD, p86 |
